udev-extraconf: update mount.sh to use /run/media instead of /media
This is done to work around the issue of auto-mounting block devices (i.e. SD cards) when root filesystem is still in read-only mode and creating /media/<device> mount-points by udev is not possible. That is due to udev (/etc/rcS.d/S03udev) getting started earlier than checkroot (/etc/rcS.d/S10checkroot.sh) gets a chance to re-mount the rootfs as read-write. Although, canonical FHS specifies /media/<device> as a mount point for removable media devices, the latest 2.3 version was released in 2004 and since then FreeDesktop/udisks and other tools adopted the new /run/media/<user>/<device> location. That was done to overcome read-only rootfs limitation, since /run is usually a tmpfs mounted partition, plus avoid name-clash between users. For our embedded systems environment we assume single-user operation and hence simplify mount point to just /run/media/<device>. But for proper per-user mounting to /run/media/<user>/<device>, some sort of session management is required along with the tool like udisks, that is out of scope of this simple udev-based auto-mounting.
